my best friend lowkey sucks right now

I lowkey just need to rant about this. I started university back in September, my best friend and I decided to go to different universities. originally she was supposed to come to me to the uni 2 hours away from our hometown but backed out last minutes because she wanted to stay in our hometown to her bf of 4 years and her family (which is completely understandable). even though she was staying at home she decided to stay on residence in dorms while she fully could have lived at her house 15 mins away from the university. when we moved we promised for her to come to my apartment and me to visit her every so often and it was going to be fine as we've been best friends for 15 years and can deal with a bit of long distance 

once she moved into dorms she slowly stated changing, she became the most basic girls in the world and all her friends seem like truly awful people, she has one friend who is a lot like me and she has decided she thinks this friend is weird and annoying. she has only come to see me once cause she dosnt want to travel here and has been SO stressed about school, like an unneeded amount of stress for what she's doing and honestly its annoying.

I went to visit for the first time in months and she almost completely ignored me, I went for the st patty day celebration and the frat parties and felt SO discluded, I have neon pink hair and dress a lot differently from them as they have bleach blonde hair and Lulu leggings and they took that as they didn't want to be near me, including my best friend. her bf talked to me and my bf that I brought the whole time (we've been friends the whole time they've been dating) and honestly it felt like she had no interest in seeing me. 

her stress levels get insane and she lets school fully take over her life every time she has something to do in school, which is hard because she dosnt awnser my simple texts asking about her for days...

I was worried about her but now honestly im just pissed off as it seems like she dosnt value out friendship. I dont know I feel like it's just hard to lose a best friend and that's what I feel like is happening.
